The Nissin Air10s wireless TTL commander that was supposed to ship on July 18th, 2017 is now going to ship on February 21st 2018 from B&H Photo. Nissin was one of the first flash makers to fully support Fujifilm, although updating their flashes was a burden because it has to be sent back to the manufacturer to update. The Nissin Air10S is supposed to alleviate that problem by having a microSD card slot, but is it too little too late?
